Bethesda's favourite ice hockey team, the nearby Washington Capitals, opened their 2018-2019 NHL season tonight, and Vault Boy stopped in as part of a Fallout 76 marketing partnership. Someone dressed up as Vault Boy sat on the passenger's side of the Zamboni during intermissions and treated fans to one of the more unexpected video game marketing campaigns this year.

According to social media reports, Washington Capitals arena announcer Wes Johnson even did Fallout voices over the PA. Pretty cool.
